To all whom it may concern: v

Be it known that I, ALBERT E. HALE, a

" citizen of the United States and a resident of Tucson, in the county of lime. and State of Arizona, have invented a new and Im-- proved Headlight, of which the following is a full, clear, and exact description.

-My invention relates to headlights for vehicles and is particularly suitable for motor vehicles. An object of the invention is to provide a simple and inexpensive headlight in which 'the rays normally directed out' of the reflector above the central plane thereof are collected by a secondary reflector within the.

main reflector to concentrate the central portion of the beam of light issued by the headlight. v

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and-claimed.

In the accompanying drawing, the figure i a longitudinal section ofa headlight embodying my invention.

1 Referring to the drawing, 4 is tlieiafnp casing, whlch is in thesha e of a hollow araboloid, theinterior sur ace 5 of which orms the reflector-of the light. A source of light 6 is located in the focus of the -re-.

fleeting surface.

. Toconcentrat the illumination in the cen-' tral part-of the headlight, I have introduced Specification of Letters Iaten'h- Application filed January 4, 1917. Serial No. 140,555.

a secondarydparabolic reflectofZfwhich a truncate ome through which. ,source of light enters the said secondaryieflec tor. The secondary reflector'is coaxial-wit the first and is' supported at the rearen'd' of the primary reflector by. a bracket 8; i

' which may be secured either to; the lamp socket as shown, onto the reflector,"-if:so desired. Thesecondar reflector is so securedthat its 'focus su stantially coincides with the focus of the primary reflector. conseguence of that arrangement any rays falling u n the secondary reflector will be dire hea'dli centre beam, which is the desired point ofconcentration.

The-secondary reflector is so truncated that it will only receive the rays from the. source of light which would not fall upon the primary reflector 4.

I claim: 'In'aheadlight of the class described, a

secondary reflector having the dome portion about the focus cut away to admit the source of light, and means for supporting the said secondary parabolic reflector with in' the first so that the secondary-reflector will receive only the rays from the some of light which would otherwise fall outside of the primary reflector.
